For the first time in its 60-year history, Rotel has released a headphone amplifier – the model is called Rotel DX-3 and will be available at the end of March 2025 for $1,499 / €1,499. The amplifier can operate with a wired connection of headphones, both in analog and digital versions (there is an unbalanced 6.35 mm jack on board, as well as a Pentaconn 4.4 mm for a balanced connection).
Rotel DX-3 is recommended for use with headphones with an impedance of 16 Ω - 300 Ω. The performance characteristics of the new product are quite impressive – the output impedance with a balanced connection is no higher than 0.6 Ω, the channel separation is 86 dB, the output sensitivity is 1.2 V, and the distortion via XLR does not exceed 0.004%.
The Rotel DX-3 amplifier can also be used with wireless headphones thanks to the presence of a Bluetooth module with support for the AAC / aptX HD codecs. The digital stream is processed by an eight-channel ESS Sabre ES9028PRO DAC chip from ESS Technology, which allows decoding PCM up to 32 bit / 384 kHz and DSD up to DSD256. Maximum resolution can be achieved via the USB-B input. The coaxial and optical inputs support resolutions up to 24 bit / 192 kHz. Volume control is possible in 0.5 dB increments using the fully differential analog NJW1195A regulator.
The Rotel DX-3 can be connected to a power amplifier or to active speakers, for which analog outputs are provided - unbalanced on RCA connectors and balanced on XLR. The Rotel DX-3 headphone amplifier is equipped with a power supply with a toroidal transformer of Rotel's own design and manufacture. Analog and digital circuits use separate power lines.

The innovative Thrax Audio Cotys phono preamplifier is presented – a model designed for fans of High-End equipment and developed in Bulgaria. The device is designed to work with MC cartridges and uses a fully balanced RIAA equalizer based on LCR filters. The innovative differential input stage and nanocrystalline inductors set a new standard for noise levels – it does not exceed 70 nV! Fully adjustable load/gain (100 – 1,000 Ohms and 50 – 70 dB) is the cherry on the cake.
Evolution Acoustics has completed a series of ten years of research and development with the release of the impressive Evolution Acoustics SYSTEM THREE acoustic system, which has become the successor to the iconic top model of the MM-series.
Sonoro has released bookshelf loudspeakers – the second generation of the famous model is called Sonoro Orchestra Slim Gen.2. The manufacturer claims the ideal partnership of the speakers with the proprietary Sonoro Maestro Smart receiver, as well as any third-party amplification
The well-known manufacturer of High-End digital equipment, SOtM has updated its own operating system Eunhasu OS (based on an upgraded Linux kernel) to version 0.5.9 (the software is used in the company's streaming products, such as the server SOtM sMS-1000SQ Eunhasu, which is shown in the photo).
The original concept of the Coturn CT-01 turntable was developed by designer Benjamin Großjohann more than five years ago. He also produced the turntable in small batches – now serial production has been organized by Thorens, and the model is called Coturn by Thorens CT-01.
